It also works well for cold-related issues such as sneezing and coughing. Cosmogan Promethazine Syrup helps prevent and treat motion sickness, nausea, vomiting, and dizziness. Doctors also recommend it to calm anxiety before surgery and sometimes to help with sleep in certain conditions.\u003C\u002Fspan>\u003C\u002Fp>\u003Cp>\u003Cbr \u002F>\u003C\u002Fp>\u003Ch2>\u003Cspan>Ingredients and Mode of Action\u003C\u002Fspan>\u003C\u002Fh2>\u003Cp>\u003Cspan>The active ingredient in Cosmogan Promethazine Syrup is promethazine hydrochloride, with each 5ml dose containing 5mg of the drug. Promethazine is an antihistamine that blocks histamine (a natural substance in the body that causes allergic symptoms). It also affects other chemicals in the brain to reduce nausea and make you feel more relaxed or sleepy, depending on the dosage.\u003C\u002Fspan>\u003C\u002Fp>\u003Cp>\u003Cbr \u002F>\u003C\u002Fp>\u003Ch2>\u003Cspan>Cosmogan Promethazine Syrup  Dosage \u003C\u002Fspan>\u003C\u002Fh2>\u003Cul>\u003Cli>\u003Cspan>Adults and children over 12 years: The usual dose ranges from 5ml to 25ml, taken one to three times daily. \u003C\u002Fspan>\u003C\u002Fli>\u003Cli>\u003Cspan>Children between 6 and 12 years are usually given lower doses. \u003C\u002Fspan>\u003C\u002Fli>\u003C\u002Ful>\u003Cp>\u003Cbr \u002F>\u003C\u002Fp>\u003Ch2>\u003Cspan>How Fast Does It Work?\u003C\u002Fspan>\u003C\u002Fh2>\u003Cp>\u003Cspan>Promethazine starts working within 20 to 60 minutes after taking the syrup.
